GRE写作成为横在中国学生的理想和现实之间的一大障碍，因此，如何攻克写作这道屏障，成为摆在我们面前的首要任务。
Finally, the manager's recommendation to replace Pat with Rosa rests on the poor
assumption that the two businesses are sufficiently similar that Rosa's experience and skill in
one business will transfer to the other. Even if Starlight's increasing profitability is attributable to
Rosa's leadership, she might nevertheless be unsuccessful leading a toy company, depending
on how much experience in the toy business is required to successfully lead such a company.
In conclusion, the argument is unconvincing as it stands. To strengthen it the manager must
show that Pat, and not some other factor beyond Pat's control, is responsible for Fancy's
declining profits. Similarly, the manager must show that it is Rosa who is primarily responsible
for Starlight's profitability, and that Rosa's abilities will transfer to the toy business. In order to
better evaluate the argument, we would need more information about how long Pat and Rosa

have served as presidents of their respective companies, and what their long-term record is for
leading their respective companies to profitability.
Argument 96
The following is a letter to the editor of a news magazine.
"Clearly, the successful use of robots on missions to explore outer space in the past 20 years
demonstrates that robots could be increasingly used to perform factory work more effectively,
efficiently, and profitably than human factory workers. The use of robots in factories would offer
several advantages. First, robots never get sick, so absenteeism would be reduced. Second,
robots do not make mistakes, so factories would increase their output. Finally, the use of
robots would also improve the morale of factory workers, since factory work can be so boring
that many workers would be glad to shift to more interesting kinds of tasks."
This editorial concludes that using robots for factory work would improve factory efficiency.
To justify this conclusion the editorial's author cites the fact that robots have been used
effectively in many space missions. Also, the author claims that the use of robots in factories
would (1) reduce absenteeism because robots never get sick, (2) improve output because
robots do not make errors, and (3) improve factory-worker morale because these workers
could be reassigned to less boring jobs. However, the author's argument is problematic in
several critical respects.
To begin with, the argument depends on the hasty assumption that the kinds of tasks robots
perform in space are similar to the ones they would perform in factories, and that there are no
differences between the two environments that would render robots less effective in factory
jobs than in space missions. Perhaps the effectiveness of robots in space missions is due
largely to the weightless environment of space. Or perhaps the average space-mission robot
performs less work than a typical factory robot would be required to perform. In either case, the
fact that robots are effective in space would amount to scant support the author's argument.
